If you have kids I would really look into Leesburg county
Many teachers who made Fairfax county one of the best schools districts moved out of the area because it became SO MUCH EXPENSIVE…
Now Leesburg is becoming stupid expensive… with the new metro, people are moving in droves. The TH i used to live I sold for 365k (1800sqf) in 2016. Now the same TH (according to Zillow) can be sold for 450+.
